چکیده مقاله
In this paper, two kinds of vibrations are considered for a composite
Timoshenko rotor: longitudinal-torsional vibration and two plane transverse one. The kinetic
and potential energies and virtual work due to the gyroscopic effects are calculated and the
set of six governing equations and boundary conditions are derived using Hamilton
principle. Differential quadrature method (DQM) is used as a strong numerical method and
natural frequencies and mode shapes are derived. Effects of the rotating speed and the …
